dio BasicsSpectrum24 devices use both electromagnetic waves to transmit and receive electric signals without wires. Users communicate with the network by establishing radio links between Mobile Units (MUs) and Access Points (APs).

Spectrum24 uses FM (frequency modulation) to transmit digital data from one device to another. Using FM, a radio signal begins with a carriersignal that provides the base or center frequency. The digital data signalis superimposed on the carrier signal (modulation). The radio signal

Introduction

Spectrum24 C

propagates into the air as electromagnetic waves. A receiving antennain the path of the waves absorbs the waves as electrical signals.The receiving device demodulates the signal by removing the carriersignal. This demodulation results in the original digital data.

Spectrum24 uses the environment (the air and certain objects) as the transmission medium. Spectrum24 radio devices transmit in the

1.4.1 CeB 1000 User Guide 3

2.4 to 2.5-GHz frequency range, a license-free range throughout mostof the world. The actual range is country-dependent.

Spectrum24 devices, like other Ethernet devices, have unique, hardware-encoded Media Access Control (MAC) or IEEE addresses. MAC addresses determine the device sending or receiving data. A MAC address is a 48-bit number written as six hexadecimal bytes separated by colons. For example:

00:A0:F8:24:9A:C8

llular Coverage

An AP establishes an average communication range with MUs called aBasic Service Set (BSS) or cell. When in a particular cell the MU associates and communicates with the AP of that cell. Each cell has a Basic ServiceSet Identifier (BSS_ID). In IEEE 802.11, the AP MAC address represents the BSS_ID. The MU recognizes the AP it associates with using the BSS_ID. Adding APs to a LAN establishes more cells in an environment, making itan RF Network using the same Extended Service Set Identifier (ESSID).

Introduction

4

BSS_IDSpectrum24 CB 1000 User Guide

APs with the same ESSID define a coverage area. The MU searchesfor APs with a matching ESSID and synchronizes with an AP to establish communications. This allows MUs within the coverage area to moveabout or roam. As the MU roams from cell to cell, it switches APs.The switch occurs when the MU analyzes the reception quality and determines that a different AP canprovide better service based on thebest signal strength and lowest load distribution.

If the CB does not find an AP with a usable signal, it performs a scan tofind any AP. As MUs switch APs, the AP updates the association table.

1.5 Direct-Sequence Spread SpectrumSpread spectrum (broadband) uses a narrowband signal to spread the transmission over a segment of the radio frequency band or spectrum. Direct-sequence is a spread spectrum technique where the transmittedsignal is spread over a particular frequency range. The Spectrum24B 1000 User Guide 5

AP-41X1 DS Access Point and the LA-41X1 WLAN PC Card adapteruse direct-sequence spread spectrum (DSSS) for radio communication.

Direct-sequence systems communicate by transmitting a redundant pattern of bits called a chipping sequence. Each bit of transmitted data is mapped into chips by the DSSS device and rearranged into a pseudorandom spreading code to form the chipping sequence. The chipping sequence is combined with a transmitted data stream to produce the DSSS deviceoutput signal.

In the United States, the three non-overlapping direct-sequence channels are channels 1, 6 and 11.

Introduction

6

Mobile Units receiving a direct-sequence transmission use the spreading code to map the chips within the chipping sequence back into bits to recreate the original data transmitted by the DSSS device. Intercepting and decoding a direct-sequence transmission requires a predefined algorithm to associate the spreading code used by the transmitting DSSS device to the receiving DSSS device. This algorithm is established when the access point and MU are Spectrum24 CB 1000 User Guide

configured. The bit redundancy within the chipping sequence enables the receiving MU to recreate the original data pattern, even if bits in the chipping sequence are corrupted by interference.

The ratio of chips per bit is called the spreading ratio. A high spreading ratio increases the resistance of the signal to interference. A low spreading ratio increases the bandwidth available to the user. The access point uses two chips per bit among three channels within the 2.4 GHz band in a pattern avoiding any 1 or 2 Mbps systems operating in the same area. The access point is capable of an 11 Mbps data transmission rate, but the coverage area is less than a 1 or 2 Mbps access point since coverage area decreases as bandwidth increases.

Introduction

Spectrum24 C

1.6 Frequency-Hopping, Spread SpectrumThe spread spectrum technique (also known as broadband) takes a narrowband signal and spreads the data signal over a broad segment of the radio frequency band or spectrum. Spectrum24 uses Frequency-Hopping Spread Spectrum (FHSS) technology for radio communication. FHSS spreads B 1000 User Guide 7

the signal by transmitting a short burst on one frequency, then jumps to another frequency for another short burst and so on. Spectrum24 uses the 2.4 - 2.5 GHz range depending on the country. This range does not require licensing from the FCC. FHSS offers a higher transmission rate than a conventional radio narrowband method.

In FHSS systems, the carrier frequency of the transmitter changes (or hops) in accordance with the pseudo-random code sequence. The code sequence dictates the frequency order selected by the transmitter. The transmitter takes the input data and spreads it in a predefined method. Each receiver has to understand this predefined method and reconstruct the signal before interpreting data. Stations in a FHSS cell hop or change the carrier frequency at synchronized intervals. Government regulatory agencies and standards, such as ETSI, MKK, the FCC and IEEE 802.11, determine the number of frequency hops (79 for the U.S.), the hopping pattern (sequence each frequency is used) and dwell time (time at each frequency). The FCC requires 75 or more hopping frequencies used and a maximum 400ms for dwell time per frequency. The transmitter and receiver synchronize to the hop sequence

Introduction

to ensure communication. The time synchronization field included in message packets coordinates the hop timing of all units. Each hop is a frequency at least 6 MHz away from the previous frequency and has a1 MHz bandwidth.Spectrum24 CB 1000 User Guide

FHSS devices can operate in an adverse environment and coexist with other devices/services in the same band. The average signal strength being relatively low on any given frequency results from FHSS. When the signal intelligence is spread out over several MHz in the frequency spectrum, the resulting power spectrum also spreads out (less than 1 watt). This results in the transmitted power spread out over a wide frequency bandwidth and makes detection very difficult without the code sequence or pattern.

Hopping provides enhanced data reception in the presence of interfering signals, like fixed frequency radio networks or microwave ovens.The system also resists interference because it spends a short time on each given frequency. If an interfering source is present or interference at a

Introduction

Spectrum24 C

specific frequency, only a small number of frequency hops are blocked rather than the entire range. With interference occurring on one frequency, the data is retransmitted on a subsequent hop at another frequency. Even if constant interference exists on a given frequency, it affects the radio network for onlya short time on that specific frequency. Although APs can share the same hopping sequence, they usually do not synchronize in time. Rarely do they

1.6.1 S2B 1000 User Guide 9

simultaneously arrive at the same frequency, referred to as contention. Interfering signals can be avoided by listening before transmitting.This reduces the probability and impact of overlapping frequencies or collisions. Although devices can hop to the same frequency, they eventually hop to different frequencies after the hop time.

In a Spectrum24 network, each AP negotiates a different hopping sequence at start-up. This allows APs to provide frequency separation and evenly divide the frequency spectrum among the units.

4 Network Topology

The variations possible in Spectrum24 network topologies depend on the following factors:

Frequency-Hopping (FH) or Direct-Sequencing (DS) network environment

the number of APs present in the network

the types of Spectrum24 radios used, 1 and 2 Mbps (FH) or 11 Mbps (DS).

Chapter 2 Operating ModesThe Client Bridge has two different operational modes, Infrastructure and Peer-to-Peer mode, and three networking ports, Ethernet, Spectrum24and RS-232.

2.1 InB 1000 User Guide 11

frastructure modeInfrastructure mode connects the CB 1000 Ethernet port with the Spectrum24 port and requires the use of an Access Point (AP). The Client Bridge connects through its Ethernet port to devices that have standard Ethernet capabilities. The Client Bridge associates with a Spectrum24 AP located nearby.The AP sees this Client Bridge/network device combination as a standard Mobile Unit (MU). The AP forms a bridge between the wired LAN and the wireless clients. In infrastructure mode, the AP is a dedicated device that is wired into the LAN back bone while the Client Bridge units can be physically moved throughout the WLAN. The Client Bridge communicates with any device on the network by routing data through the associated AP. Multiple APs with the same ESSID can be placed within the same area. The 802.11 standard enables the Client Bridge to roam among the MUs and APs. Reassociation occurs as long as the Client Bridge has the same ESSID asthe AP it is trying to associate with.

2.5 International Roaming OperationEnable the international roaming mode to automatically adjust the CB 1000 to the country in which it operates. The CB 1000 requires association with an

2.6 DB 1000 User Guide 15

AP to provide country information. To enable International Roaming mode, select International Roaming in the Radio parameter window. After power up, the CB 1000 listens on several channels for 802.11 traffic. When it recognizes a valid frame, it sends an international probe and waits for an international probe response (IPR). If an IPR is received, the CB 1000 copies the appropriate country parameters to the RAM table and adjusts its hopping sequence table. At this point, the CB 1000 can associate with the AP.

The CB 1000 keeps the country parameter information as long as it is associated to the AP sending the IPR.

An associated CB 1000 probes the AP for a new country code after 20 minutes.

ata EncryptionMobile nodes and other hosts can be a target of information theft.This occurs when unauthorized users eavesdrop on a network to glean proprietary information. The absence of a physical connection makes wireless links particularly vulnerable to eavesdropping.

Encryption becomes the most efficient method in preventing information theft and improving data security. Encryption requires scrambling and coding of information, typically with mathematical formulas called algorithms,before the information is transmitted over a communications link or network. An algorithm is a set of instructions or formula describing how to scramble and encode the data. A key is the unique code used by the algorithm to encrypt or decrypt the data. Decryption is decoding and unscrambling the received encrypted data.

Operating Modes

The same device, host computer or front-end processor, usually performs both encryption and decryption. The data direction determines which function, encryption or decryption, the device performs. The device takes plain text, encrypts and scrambles the text typically by mathematically combining the key with the plain text as instructed by the algorithm, then transmits the data over the network. At the receiving end, another device Spectrum24 CB 1000 User Guide

unscrambles and decodes the encrypted text revealing the original message. A user can know the algorithm, but cannot interpret the data without the key. Only the sender and receiver of the transmitted data know the secret key.

Symbol uses the Wired Equivalent Privacy (WEP) algorithm, specified inIEEE 802.11 section 8, for encryption and decryption. WEP uses the same secret key for both encrypting and decrypting plain text. Typically, an external key management service distributes the secret key. Symbol recommends that users regularly change keys for added security.

IEEE 802.11 defines two types of authentication, Open System and Shared Key. Open System authentication is a null authentication algorithm. Shared Key authentication is an algorithm where both the AP and the MU share an authentication key to perform a checksum, an error-checking operation, on the original message.

By default, IEEE 802.11 devices operate in an open system network where any wireless device can associate with an AP without authorization. A wireless device with a valid shared key is allowed to associate with the AP. Authentication management messages, also called packets, are unicast, meaning authentication messages transmit between only one AP and one MU, not broadcast or multicast.

7.1.2 Flow Control

Flow control adjusts the flow of data from one device to another.This ensures the receiving device can handle all of the incoming data.Flow control becomes an important factor when one of the devices is capable of transmitting data at a rate faster than the other can receive it. There are two basic types of flow control, Hardware and Software.

7.1.3 H

7.1.4 SoSpectrum24 CB 1000 User Guide

ardware Flow Control

Hardware flow control uses dedicated signal lines to dictate transmission of data and has two options that allow selecting which pair of lines to use for this type of flow control:

RTS/CTS - Request To Send/Clear To Send

DTR/DSR - Data Terminal Ready/Data Set Ready

The Windows flow control setting, Hardware, uses the RTS/CTS pair of flow control lines.

ftware Flow Control

Software flow control uses two special characters, Xon and Xoff. Xon and Xoff are embedded in the data. These special characters instruct the computer to start and stop sending data. In the incoming direction, flow control prevents the CB 1000 from sending data when the computer is not ready. Enabling incoming flow control, enables the CB 1000 to interpret Xon/Xoff characters in the data stream as flow control signals. The Xon/Xoff characters are not considered part of the data.

The outgoing software flow control option specifies the generation of Xon/Xoff flow control characters by the CB 1000. The control characters are sent out the serial port and instruct the computer to start or stop sending data. This option prevents the computer from sending data when the CB 1000 is not ready to accept it.


Spectrum24 C

Software flow control can have both incoming and outgoing mechanisms running simultaneously, individually, or not at all (this is the default).

rial Packets

The serial packets parameters control the serial to network packetconversion process. Adjusting the default settings is not necessary for the Serial Packet Parameters. These parameters control the way that data received on the serial port is divided into Ethernet packets. The Ethernet packets are sent to serial application network connection. For specific information about the effects of the serial packet parameters seeChapter 11 Serial Stream To Network Packet Conversion on page 71.

Spectrum24 C

Chapter 8 Serial Port Protocol ConfigurationThis chapter describes how to configure the CB 1000 serial port protocols. When a Client Bridge receives a message from the serial port, the Client Bridge turns the message into a series of network packets. The transmitting

8.1 RM

8.1.1 CoB 1000 User Guide 49

Client Bridge adds the originating port address, the destination port address and other critical information to each packet. When the transmitting Client Bridge finds radio silence, the Client Bridge sends the packets. RMP Pipe is used in situations that require real time or high-reliability data transfer.TCP Pipe is useful in situations when poor radio reception is a problem.RMP Pipe is the preferred protocol for Serial Line Replacement applications.

P PipeFor applications where an RS-232 serial cable is being replaced by a pair of CB 1000s, or when CB 1000s are being used to form a broadcast topology (data is sent to all CB 1000s), the RMP Pipe protocol is used. In the RMPpipe protocol, the CB 1000 accepts a stream of data at its serial port and transmits it over the network to one or more receiving CB 1000s. When the data arrives at the receiving CB 1000, it is sent is out the serial port.

The RMP Pipe protocol sends data to the receiving unit as though CB 1000s were connected via serial cables. The data is not filtered or interpreted by the CB 1000s. Use this protocol when the CB 1000 is used as a drop-in replacement for a serial cable.

The RMP Pipe protocol has several configuration options that are designed to optimize data throughput and minimize packet loss according to the needs of any particular system.

Spectrum24 C

8.1.2 RMP Pipe Parameters Source Address

The RMP address is used to identify the CB 1000s when sending serial data to each other. The RMP Pipe value of default enables the CB 1000 to useits unique serial number as the RMP address. It is not necessary to change B 1000 User Guide 51

this setting.

Source Address Filter

The CB1000 only accepts data coming from the specified address. For example, if the entry is set to 1234, only data originating from a CB 1000 with the RMP address of 1234 is accepted. All other data is ignored. The default value none allows data from any RMP address to be accepted. Change the Source Address Filter value only when there are multiple RMP Passthrough Serial Line Replacement installations in close proximity.


52

Destination Address

The CB 1000 sends data received on the serial port to this address.Enter the RMP address of another CB 1000 for direct serial linereplacement. Other possible values are dynamic (default) or broadcast.The dynamic value returns data to the CB 1000 data was received from. Using the value of dynamic allows two CB 1000s to communicate to each Spectrum24 CB 1000 User Guide

other. Entering broadcast sends data to all CB 1000s set to use RMP Pipe.

Transmit Try Count

For dynamic data, this count specifies the number of attempts the CB 1000 makes to transmit each RMP packet of data. Ensure the CB 1000 is inrange and powered up to reduce the possibility of transmission failures. When failures occur, data is lost if additional attempts are not made. This count allows the user to specify how many attempts to take atre-transmitting data. The maximum is 65,000 retries. The default is infinite, which causes each packet to be retried until successfully sent. Select the Transmit Try Count based on the sensitivity of the application to data delay and/or data loss.

Transmit Retry Interval

This setting determines the time period to wait between re-transmission attempts. The value is specified in 1/100ths of a second, 100 (default) equals 1 second. The maximum value is 65000.

I/O Control

I/O control is only relevant to serial line replacement applications that use the RMP protocol. I/O control defines control over digital inputs and outputs of the CB 1000 separately from the data lines. Digital input and output are shared with the flow control lines (RTS, DTR, CTS, and DSR), but in this mode the CB 1000 does not interpret them as flow control signals. They give the ability to send digital data from one device to another without interpretation by the CB 1000. Use of Hardware Flow control on lines that have been enabled for I/O Control is not allowed.


Spectrum24 C

8.2 TCP PipeTCP Pipe, similar to RMP Pipe, makes no changes to the serial data stream. TCP Pipe differs from RMP Pipe by creating two independent network connections for transmitted and received data. Using two connections allows each CB 1000 to detect conditions when it has lost radio contact with theB 1000 User Guide 53

8.3 Network Serial Port ConfigurationThis section describes how to configure the CB 1000 as a network serial port. This is a standard configuration for connecting a client serial device with a network server. Connection to a network serial port is accomplished overa TCP/IP socket connection. Any program that uses standard TCP/IP network Spectrum24 CB 1000 User Guide

sockets can communicate with the serial port of the CB 1000. Once asocket is established to the CB 1000, any data written to the socket is sent out the serial port and any data received by the serial port is returned via the socket connection.

The CB 1000 network serial port may be used in two modes:

TCP Listen Port

TCP Connect Port.

In the TCP Listen Port mode before any serial communication is possiblethe socket connection is made by the network program for the CB 1000 to communicate. For example, use the TCP Listen Port if a central server expects to open a TCP/IP socket connection to the CB 1000. In the TCP Connect Port mode the CB 1000 establishes a socket connection to the IP address and port number specified in the configuration. For example, use the TCP Connect Port if the system expects the CB 1000 to open a TCP/IP socket connection to a central server.

The following procedures configure CB 1000 as a network serial port.

1. Complete the configuration of the basic radio settings instructions in6.1 Configuration of the Radio Settings on page 37.


3. Complete the General Configuration instructions 7.1 General Serial Configuration on page 44.

1. Click on the wait for keystroke button.

2. Enter the IP address of the device the CB 1000 establishes a telnet connection to in the Connect to IP field.

3. The default Connect to port value, 23, is the industry standard port number for telnet connections.

4. Leave the Reconnect After Shutdown box checked to allow a new session after closing an active one.



64

9.2 Command Prompt ConnectionThis section describes the command prompt connection method for aserial telnet client. The command prompt connection method provides a telnet prompt to the serial terminal. From the telnet prompt, the user can open a telnet session to any computer or device that is accessible on the Spectrum24 CB 1000 User Guide

network and is capable of accepting telnet connections.

To establish a telnet connection, at the command prompt type the command open followed by the IP address of the host computer or device (for example telnet> open 10.10.10.129). The IP address can optionally be followed by the TCP port number on which to open the connection. If the port number is omitted, the industry standard, default telnet port number of 23 is used.

Use the IP address, not the name of the host since only IP addresses are recognized by the CB 1000. When the telnet connection is closed, theCB 1000 displays a new telnet prompt.

The Line Printer Daemon (LPD) protocol requires an operating system that supports LPD to a remote host such as Windows. The LPD server on theCB 1000 uses a uni-directional protocol. Data is received via a wireless network connection and sent out the serial port to the printer. Data received from the serial port is ignored. This means the CB 1000 ignores data received from the printer except for software flow control characters(see 7.1.4 Software Flow Control on page 46).

Use the network hostname or IP address of the CB 1000 as the remote printer host when configuring the operating system.

Serial Stream To Network Packet Conversion

Spectrum24 C

Chapter 11 Serial Stream To Network Packet ConversionThe serial port on the CB 1000 can be used for a range of different applications, though almost all applications involve bridging data between B 1000 User Guide 71

the CB 1000 serial port and one of the network interfaces. Data that is received on the serial port is packetized, then transmitted on either the radio or wired network interface to the network device configured to receive serial data. This section explains the process of packetizing data received on the serial port.

Network devices transmit and receive data in a fundamentally different way than the serial port. Network devices operate on packets whereas serial devices operate on single characters. A network packet is a well-defined structure that includes enough information for the packet to be interpretedby different network devices, routed to the appropriate destination, and interpreted by the destination application. Each network packet carries some amount of application data. In the case of network packets for serial port applications, this data is the information that was received or should be transmitted on the serial port.

Data transmission between serial devices is simpler. The most basic difference is that there is no requirement for data to be sent in well-defined packet structures. Each device sends serial data one character at a time.The other device must receive and process each character as it is received. Additionally, since serial communication is between two devices, there is no need to include information about the source and destination of the data. The CB 1000 interprets the serial data stream, collects it into data groups and then forms network packets with this dataand transmit the packet to the network device which is set to receive theserial information.


72

The CB 1000 uses three user-configurable parameters to segment the serial character stream into groups of data for network packets. These parameters, line length, timeout, and delimiters, are described below. Keep in mind that the CB 1000 always uses all three of these parameters and when the conditions of any one of them are met a network packet is generated.

11.1 Li

11.2 Ti

11.2.1 DeSpectrum24 CB 1000 User Guide

ne LengthAs data arrives on the serial port it is accumulated in a buffer in theCB 1000. The Line length parameter sets the maximum size for this buffer.When the number of characters in the buffer reaches the Line length value the entire buffer is sent as the data in a single network packet. The value of Line length can range from 1 to 1408 bytes. The default value is 1408.

meoutSerial data arrives in small bursts of characters. When the CB 1000 receives a burst of data and waits for a period of time for additional data to be received. When additional data is received, it is added to the receive buffer, and the CB 1000 begins to wait again. If additional data is not received for longer than the period specified by the Timeout value, then the buffer of characters received is sent in a single network packet, and the process begins again. Specify the timeout value in 10 millisecond increments. The valid range for timeout is from 10 milliseconds (0.01 second) to 65000 milliseconds (650 seconds). The default value is 10 milliseconds.

limiters

Some serial devices transmit and receive data in a known structure. In these cases there are often special characters that the transmitting device uses to indicate a complete message has been sent. These characters are referredto as delimiters. Specify up to five different delimiting characters to the CB 1000. When the CB 1000 adds one of these characters to the buffer of serial received characters the CB 1000 immediately sends that buffer as a network packet.
